Parts of Phoenix Sky Harbor International Airport were closed due to police activity Sunday morning.
Phoenix police officers noticed an unattended vehicle shortly after 7 a.m. The car, which was later determined to be a rental, was parked along the curb at Terminal 4 and a bomb squad was called to the scene.
This created a line of stopped cars heading into Terminal 3 and 4.
During a media briefing, Phoenix Police Sgt. Tommy Thompson said Terminal 4 was shut down and that the incident had disrupted a number of flights.
